AWS for Industries
Where energy meets efficiency: Modernize HPC workflows with Leostream on AWS
High performance computing (HPC) is a cornerstone of innovation in the energy sector. As data volumes grow and geophysical workflows become more compute-intensive, the energy industry is moving beyond traditional on-premises systems toward flexible, cloud-hosted HPC solutions. However, managing sprawling environments across cloud and on-premises platforms can become an operational burden.
Teams must balance performance and cost while managing user access, provisioning virtual workstations on demand, and maintaining a high level of security. Admins often struggle to onboard new users quickly or provision compute resources dynamically. Without the right orchestration layer, these environments can quickly become fragmented, expensive, and difficult to manage.
A modern HPC architecture doesn’t start and end with compute—it also requires efficient HPC cluster management, granular access control, and dynamic infrastructure provisioning. That’s where Leostream comes in. Acting as the connection and control layer between users and Amazon Web Services (AWS) hosted high performance compute environments, Leostream consolidates how enterprises deploy and manage virtual desktops and HPC GPU resources at scale.
Leostream on AWS
Leostream is a leading AWS Partner specializing in remote access solutions and virtual desktop infrastructure (VDI) management. The Leostream platform provides enterprises with a vendor-agnostic solution for managing and connecting users to workloads running in AWS environments, including Amazon Elastic Compute Cloud (Amazon EC2) instances and Amazon WorkSpaces. With Leostream organizations can implement hybrid cloud strategies by centralizing the management of on-premises and AWS-hosted resources through a single administrative interface.
These solutions are particularly valuable for industries requiring high-performance remote access to graphics-intensive applications, such as media production, engineering, and healthcare. As an AWS Partner, Leostream helps customers optimize their AWS deployments for remote work scenarios while maintaining security, compliance, and cost efficiency.
Cloud-native HPC for the Energy Industry
Energy companies face growing demands for agility in geophysical modeling—from oil and gas exploration to renewable energy development and resource optimization. Many have adopted Amazon EC2 as their cloud HPC backbone, providing the essential compute infrastructure for complex engineering simulations.
However, as usage expands across projects, teams, and global locations, the challenge shifts from provisioning compute to orchestrating access efficiently and securely. Adding a centralized management layer with Leostream provides these enterprises with the capability to streamline access and automate resource provisioning. They also gain full visibility into every session, solving the complexity of user orchestration across entire cloud HPC environments.
Energy companies transitioning to cloud-based HPC commonly encounter several obstacles. Underutilized on-premises infrastructure generates mounting costs while organizations maintain both legacy and cloud systems. Manual provisioning creates delays—technical teams sometimes wait weeks to access resources. Security concerns multiply as unmanaged access points create vulnerabilities across distributed systems, particularly when teams span multiple geographic regions and regulatory jurisdictions. And capacity planning becomes a balancing act between over-provisioning that drains budgets and under-provisioning that hampers productivity.
Deploying Leostream on AWS can transform how energy companies manage computational resources:
- Virtual desktops spin up only when needed, maximizing Amazon EC2 utilization and minimizing idle runtime—directly impacting the bottom line for organizations running continuous simulation and modeling operations.
- Geoscientists and engineers can connect to high-performance workstations in minutes rather than days, so technical teams are able to focus on core work instead of waiting for infrastructure.
- Centralized policy enforcement and federated identity management can strengthen security across projects and geographies, while facilitating regulatory compliance.
- By eliminating custom scripting and homegrown tools, IT teams can focus on strategic initiatives rather than maintenance.
The Leostream architecture on AWS is shown in Figure 1. The Leostream Connect client or web portal creates the user’s Amazon DCV session (Step 1), orchestrated by the Leostream Connection Broker communicating with the Leostream Agent on the Amazon DCV server (Step 2). Once created, the end user’s web or OS-based Amazon DCV client connects to the backend Amazon DCV server’s session (Step 3). Session traffic depicts the end user’s egress traffic from their Amazon DCV server, with both Amazon DCV servers and the Connection Broker secured in private subnets and accessed through the Leostream Gateway.
The integrated capabilities of Leostream enhance this architecture for energy industry requirements. SAML 2.0-based single sign-on (SSO) authentication integrates with enterprise identity providers, confirming secure access and compliance with internal policies and external regulatory requirements common in the energy industry. Dynamic pooling automatically provisions virtual desktops based on user roles and workload requirements, scaling in near real-time as demands shift from initial exploration through detailed reservoir modeling. Automated power management intelligently controls instance states based on usage patterns. This significantly reduces cloud spend without compromising access to critical resources needed for time-sensitive analysis.
Fine-grained access policies provide least-privilege access based on group membership and project roles, eliminating credential sprawl while maintaining the flexibility energy companies need for collaborative, cross-functional project work. A centralized administrative console gives IT teams complete visibility into sessions, resource pools, and provisioning rules from a single interface, dramatically improving system utilization insights and reducing response times when technical teams require support.
